Software Engineering. Most software is basically just houses of cards, developed quickly and not maintained properly (to save money ofc). We will see some serious software collapses within our lifetime.

I used to be a funeral director. The majority of outsiders were unaware of pretty much everything we did. Often on purpose because thinking of death is uncomfortable.

The biggest “secret” is probably that the modern funeral was invented by companies the same way diamond engagement rings were. For thousands of years the only people who had public funerals were rich and famous. It was the death of Abraham Lincoln that sparked the funeral industry to sell “famous people funerals at a reasonable price”. You too could give your loved one a presidential send off! The funeral industry still plays into this hard, and I’ve found many people are simply guilt tripped by society to have a public funeral.
